Message from the Department Head
Hello! I hope that you
are staying healthy!
We've all gone
through an unusual
pandemic year.
In 2020-21, Purdue
provided masks, face
shields, hand
sanitizers, regular and
surveillance testing for
COVID-19, rooms for
quarantine, weekly
tips for well-being… Classrooms were at
diminished capacity to enable physical
distancing of at least six feet. Attendance in
classes was optional, class activities were
recorded for absent students, many classes
were completely online. In the fall semester
some face-to-face classes rotated student
attendance, and in the spring, we increased the
number of face-to-face classes and moved them
into larger classrooms. Most office hours were
online, and the Math Resource Room switched
to various online forums; the advantage of
online forums is that anybody can post an
answer at any time and that answers remain
visible to those who come later. Our faculty
and teaching assistants worked hard to adapt
their class meetings for the online and hybrid
activities, to respond to email and forum
queries, to write different exams, to
accommodate students in quarantine. What
was missing, of course, were the live
interactions that add so much to learning
We have much to celebrate. Twenty-four of
our graduate students finished with a Ph.D.,
five with Master’s degree, and 192 with the
Bachelor of Science degree (this counts both
mathematics and actuarial science majors).
This fall we will have 21 new graduate
students, for a total of 137.
In the coming year we will have a new
undergraduate major within the
department: we now join the Computer
Science and Statistics department to offer a
data science major. New courses were
developed by Professors Mimi Boutin,
Guang Lin and Jon Peterson.
Purdue came out of 2020-21 strong: we had
no infections in any classrooms or labs, and
our incoming class of more than 10,000 new
students is larger than ever, giving us a huge
vote of confidence. Most of the incoming
students are in engineering and STEM
disciplines, which means that we will be
running even more mathematics classes.
This summer we hired five new continuing
lecturers; these are permanent non-tenured
positions for teaching our heavily enrolled
100- and 200-level courses. Permanency
allows us to offer consistent high-quality
instruction for years to come.
In the spring we hired three new tenure-
track professors, two professors of practice
and six Golomb Visiting Assistant
Professors. This fall we are switching to
pre-pandemic classroom density and modes
of classroom instruction, while wearing
masks and sanitizing our spaces. The goal
is still excellence of instruction, plus staying
safe. You stay safe as well!

Awards and Honors
Tess Anderson Honored with 2021 Violet Haas Memorial Fellowship
Assistant Professor Theresa (Tess) Anderson is a mathematician and advocate, whose work in both
areas centers around building new bridges. Her advocacy centers around underrepresented minorities,
particularly people of color and women.
Tess Anderson’s mathematics lies at the interface of harmonic analysis and analytic number theory, and is
funded by a National Science Foundation grant jointly in the two (seemingly) separate areas of Analysis
and Algebra, Number Theory and Combinatorics. In one instance, she uncovers number-theoretic
structure in analysis related to a broad range of applications, such as X-rays and musical scales, but the
dialogue between these fields goes both ways and in many directions. She is the 2006 Presidential
Scholar from Wisconsin, and holds Bachelors degrees in Mathematics, Chemistry, and Spanish from the
University of Wisconsin, and a Ph.D. in pure Mathematics from Brown University.
The award is named for Violet Haas, an electrical engineering professor at Purdue University from 1962 to 1986, who was
instrumental in the early development of the Purdue chapter of the Society of Women Engineers. The fellowship is to support the
science and engineering careers of junior female faculty with children.
Jay Akridge, provost and executive vice president for academic affairs and diversity, presented the award along with co-host
Mangala Subramaniam, director of the Susan Bulkeley Butler Center for Leadership Excellence and professor of sociology
virtually on March 9, 2021.
Jim McClure awarded 2021 Focus Award
Professor James (Jim) McClure is a Professor of Mathematics and Curriculum & Instruction. He
has been with Purdue University since 1992, he has taught a wide variety of courses, and from
2014 until this summer he was the Associate Department Head. Over the years, he has worked
closely with the Disability Resource Center to ensure that all students received the best education
possible, constantly looking for unique ways to say “yes” to access when others would say “no.” He has established an open and collaborative relationship with Purdue’s Disability Resource Center. Through this relationship, he has continued to promote the philosophy that access is a
shared responsibility at Purdue University.
When barriers arise to accessibility for students in mathematics, Jim McClure takes action to assist his students, and shares his
ideas on how the university can work to reduce or eliminate those barriers. He looks for innovative and creative ways to support
student access and participation, and he recognizes that effective student access can look different for each student.
Jim McClure continually goes above and beyond when it comes to providing access to students. He understands that the ADA is
the foundation for accessibility, but not the ceiling. He has been invaluable in the process of converting typically highly visual
subject matter into a medium that provides students wider access.

to 12 assistant professors (or recently promoted associate professors) for demonstrated talent for teaching, as well as three
senior faculty members for long-term contributions to teaching and mentoring at the University.
The Department of Mathematics is highlighting mathematical art work by our Graduate Students
Graduate student Matthew Weaver used pine to create a digital image of the
Whitney Umbrella, shown here. It is displayed on the 8th Floor of the
Mathematical Science Building next to office 822.The Whitney Umbrella is a
self-intersecting surface in affine space and is the classical example of a pinch-
point singularity. Named after Hassler Whitney, this surface is often depicted
with the negative z-axis serving as the “handle” of the umbrella.
Matthew goes on to say, as a "commutative algebraist, my research directs me
to the study of the equations and algebraic structures associated to geometric
varieties like the one shown here. However, one cannot help but appreciate the
geometric nature of these objects. Details such as tangents, intersections,
smoothness, etc. have their algebraic translations, but there is something intrinsically
satisfying one only obtains from visualizing such an object or even using one’s imagination. For instance, my own research
relates to the resolution of singularities using blowup algebras. If I were to resolve the singularities here along the z-axis, I
would have to figure out how to “open up the umbrella”.

Mathematics Student wins NSF Graduate Research Fellowship
Garrett Mulcahy, class of 2021, won an NSF Graduate Research Fellowship.
Garrett is from Elmhurst, IL. He double majored in mathematics and statistics and hopes
to become a research mathematician, either in academia or at a national laboratory.
Garrett will use the NSF Graduate Fellowship at the University of Washington pursuing
a Ph.D. in mathematics (with an interest in analysis and probability). The Fellowship will allow Garrett to continue the research
project he worked on with Professor Thomas Sinclair. The project goal is to use techniques from random matrix theory to better
understand the connection between quantum expanders and a class of matrices we proposed called malnormal matrices.
“I would especially like to acknowledge how grateful I am for the support and mentoring of Dr. Thomas Sinclair, Dr. Mark Ward,
and Dr. Steve Bell throughout the application process as well as my whole time at Purdue”.
National Science Foundation Graduate Research Fellowships Program (GRFP) recognizes and supports individuals early in their

memories of the math department, especially of the coffee and cake in the library lounge before
colloquiums, and the ritual of lunch at the Union with professors Craig Huneke and Bill
Heinzer, and also other members of the research group. After a two-year post-doc position at
Michigan State University, where Bernd Ulrich was his mentor, Professor Raghavan returned
to India.
His research interests have since changed somewhat---to representation theory of groups and
related geometry and combinatorics---but the friendships forged during his graduate school
years continue unchanged.
“I find myself reading it (PUrview) whenever I reminisce about my long-lost freedom in
college. Not a day goes by without being grateful for the time I spent at Purdue, and
the Ph.D. degree I received under the mentorship of Laszlo Lempert in 2014,” said
Tamas Darvas.
Since leaving Purdue, Dr. Darvas has been at the University of Maryland, first as a
postdoctoral research associate between 2014-2018, then as an assistant professor 2018-
2021. This past spring he was promoted to associate professor. During this time Dr.
Darvas received an NSF CAREER Award in 2018 and an Alfred P. Sloan Fellowship in
2021.
Dr. Darvas lives in the DC area together with his wife, Timea and their daughter, Anita.

Dr. Tiziana Giorgi is currently a program rotator at the NSF, working in the Applied Math Program in Alexandria, Virginia,
and Dr. Robert Smits is guiding his third doctoral student through a thesis in Las Cruces, New Mexico. Their paths, now
convergent, sometimes divergent, are strongly recurrent.
Drs. Giorgi and Smits first met at Purdue when they were learning the intricacies of the Hardy-
Littlewood maximal operator and averaging properties in Real Analysis II. After passing
qualifying exams, they decided to get married over a Spring Break in Rome, Italy. Tiziana went on
to take a PhD in Applied Partial Differential Equations under the supervision of Daniel Phillips
(1997) and Robert took his doctorate in Stochastic Differential Equations with Rodrigo Bañuelos
(1996). Their daughter, Georgia was born as they were finishing their theses, just in time to make
the mentions.
After graduation, Tiziana received a Postdoc at McMaster in Canada,
while Robert held one at Syracuse, a bit more than 3 hours away. They first solved the 2-
body problem with independent positions at Towson University, a predominantly teaching institution
in Baltimore before moving to research positions at New Mexico State in 2002, where they joined
fellow Purdue Alum, Dr. Irena Swanson, and buying her house shortly before she moved to Reed
College. They are active in teaching and research, running departmental seminars and travelling
extensively including sabbaticals at Sapienza University of Rome, a Fulbright Fellowship in Lisbon,
the ICIAM meeting in Beijing and an untold number of SIAM and AMS meetings. They work
regularly at NMSU with two other Purdue Alums, Louiza Fouli and Jonathan Montaño.
Tiziana has received 3 NSF Research Grants for her work on superconductors and liquid crystals while Robert has done research
for the NSA and the USAF involving large deviations. Tiziana loves her work as program rotator at the NSF, getting to impact
not only the intellectual developments in Applied Math, but also to help make it more available to a wide diversity of talented
mathematicians. Robert meanwhile is content to work with students on averaging properties and maximal operators, re-purposing
the techniques of Analysis II for new problems as well as directing the Actuarial Science concentration. Their daughter Georgia
is a doctoral student in statistics at Cornell University.
